Which consequence results when electron orbitals hybridize incorrectly in cytochrome oxidase?

A)Decreased oxygen reduction ATP synthase activity
B)Accelerated protein folding chaperone availability
C)Increased superoxide dismutase mRNA expression
D)Enhanced oxidative phosphorylation uncoupler selectivity

💡 Explanation

Incorrect hybridization alters the catalytic site geometry, leading to decreased oxygen binding and thus reduced function; therefore, oxidative phosphorylation is impaired rather than enhanced, because electron transfer is altered, rather than superoxide production.
